Abstract

Drying methods of green panic seed were investigated for obtaining better germination, because the methods might have remarkable effects on seed germination afterward, as suggested in some experimental results. It was recognized that drying speed played decisive role as well as drying temperature for controlling germinating behavior of seed. Rapid seed drying injured germination, and the injurious effect occurred in an early stage of drying after harvest, affecting to a portion of seed except bract. Germination of seeds dried at 30℃ or 40℃ were better than those of seed dried at 20℃ or 15℃, when the seeds had been dried slowly at these temperatures just after harvest. Germination percentages of seeds dried at 20℃ or 15℃ decreased with time of storage for longer than one and a harf year at room temperature. Decreasing rates were higher in seeds stored at 30℃ than at room temperature. Those seeds showed high germination percentages and rapid germination, provided their bracts had been removed. Seed stored at 30℃ for 2 months in wet condition could not germinate at all. But seed stored at 20℃ or 15℃ in the same conditions showed very good germination several months after harvest. Excellent germination was produced 7 months after harvest, if the seed had been dried very slowly for a month at 20℃. From these results, two methods of slow drying of seed immediately after harvest were shown for obtaining excellent germination afterward as early as possible ; 1) Drying for several days at 30℃ in a shallow tray. But there was a risk of failure in this method by inadequate drying speed. 2) Drying for a month at about 20℃ in a vessel, and stirring seed at intervals of some days to dry all grains uniformly.
